Mediterranean sea?

Question

8 years ago when I went to the mediterranean sea in Turkey, the coast was a very light blue in some areas. Since now the area is a little more populated, has it changed?

Answer 1

I am not sure what you are asking, but the blue color is the reflection from the sky, water is, in fact, colorless.  However, if you are standing on the shore, the water nearest to you will seem like a lighter blue because it is shallower, the water out further will seem darker blue because it is deeper, and that is the reason for the color changes.  Population has nothing to do with the color of the water!  Maybe there is less room to stand on the beach, but the water color is probably very much the same!  Except now, you need to take into account the climate change effects, and the melting ice caps!
